I haven't read back through the posts, so this is probably a repeat of previous stuff. 6 years ago last month, I tried Chantix.
I quit the first week of the pills. I finished the course. My wife smokes all the time, but even with that, I still don't want a cigarette.
I know some people have side effects ... but if you can last the course, it might work for you like it has for me.
